Trying to do a WMS GetFeatureInfo request results in an error such as:

(on a local instance of MapServer)

or

Parameter X(or Y,I,J) out of scope
(on a remote ArcGIS service)

With a request like:

Can you provide the full URL of the endpoint? what is the endpoint? mapserver? geoserver? else?

#3 Updated by Giovanni Manghi over 6 years ago

Does the same endpoint work as expected on 2.18.14?

The following MapServer WMS has the issue on: QGIS version 2.99.0-Master QGIS code revision af5b2a750a

http://ogc.bgs.ac.uk/cgi-bin/TFL-PSI/ows?

The same service works on: QGIS version 2.18.3 QGIS code revision 77b8c3d

Here's an example GFI that works on the service:

http://ogc.bgs.ac.uk/cgi-bin/TFL-PSI/ows?language=eng&REQUEST=GetFeatureInfo&SERVICE=WMS&VERSION=1.3.0&LAYERS=GBR_Stoke-on-Trent_ESA_EN_5k_psi_TS&STYLES=&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE&CRS=EPSG:4326&BBOX=53.0052235378464,-2.28573545848794,53.1251768672774,-2.13175281574312&WIDTH=1086&HEIGHT=846&QUERY_LAYERS=GBR_Stoke-on-Trent_ESA_EN_5k_psi_TS&i=337&j=255&info_format=text/htmlx%x%

The following ArcGIS service is the service in the report:

https://map.bgs.ac.uk/arcgis/services/GeoIndex_Onshore/hydrogeology/MapServer/WmsServer?

GFI works on: QGIS version 2.18.3 QGIS code revision 77b8c3d

The following GeoServer service doesn't work on: QGIS version 2.99.0-Master QGIS code revision af5b2a750a

http://ogc.bgs.ac.uk:80/digmap625k_gsml_insp_gs/ows?

It works as expected on: QGIS version 2.18.3 QGIS code revision 77b8c3d
